PORTABLE HOT-FLUID HEATING APPARATUS.

Specification of Letters Patent.

Patented April 28, 1908.

To all whom t may concern:

Be it known that I, HENRY THEODORE OFF- TERDINGER, a citizen of theUnited States, residing at INlashington, District of Columbia, haveinvented new and useful Improvements in Portable Hot-Fluid HeatingApparatus, of which the following is a specification.

My invention relates to improvements in portable hot fiuid heating`apparatus, of the radiator type 5 that is to say, apparatus in whichfluid is caused to circulate through a series of radiator sections, thecombined sepltions making up the radiator being porta e.

The object of the invention is to facilitate heating the circulatingbody of fluid in a manner and by a means associated with one of thevcolumns or legs of the radiator.

Radiators of the type to which this invention is directed are chiefly,although not eX- clusively, useful to heat rooms or apartments, separateand apart from a permanent system designed to heat various rooms orapartments of a building. Such portable a paratus may be moved fromplace to place of a building, and used wherever there be a connectionfor fuel, such as gas from an ordinary gas fixture, or the like. whichsuch ap aratus is ordinarily designed, it is a materia considerationthat the circulatino body of fluid may be quickly and intensely heated,and it is also desirable that the radiator present the customary neatand ornamental appearance of such devices. Both considerations are fullymet in an apparatus constructed according to my present invention.

IVith the foregoing objects in view, the invention consists in aportable hot water apparatus or radiator possessing the featureshereinafter described and illustrated in the accompanying drawing.

That which is regarded as new will be set forth in the clauses of claimappended to the description.

In the accompanying drawing illustrating that which I regard as the bestknown embodiment of my inventionMFigure l is a part elevation'and partsectional view of a radiator provided with my invention, Fig. 2 is anendview; Fig. 3 is a horizontal sectional view 5 and Fig. 4 is adetailperspective of the burner. y

In the uses forv In the said drawing the reference numeral 1 designatesa hot water radiator which consists of numerous heat radiating columnsthrough which the water is caused to circulate, and which, not beingconnected, with the stationary heating system may, if desired, beprovided with an extension box or tank 2. In the drawing I haveillustrated a radiator of the three-column type. One of' the columns orlegs, for instance the central leg of one end section of the radiator,is modified in its construction to present a tube 3 having opposite,parallel, relatively wide, closely associated walls 4, and connectingend walls, constituting a fluid passage communicating at its upper andlower ends with the circulation passages of the radiator structure, andcharacterized by the fact that the water which passes therethrough iscompelled to assume the form of a film, the attenuated character ofwhich is most susceptible of responding to the,influence of heat ap liedto the tube, through which it passes, an which will be referred to asthe heating tube. Oombined with the heating tube, to surround the same,is a burner 5, the jet orifices 6 of which extend across and in closerelation tothe broad fiat walls 4, of the heating tube. This burner ispreferably, and as shown, of the Bunsen type, having a conduit S for thesupply of fuel, such as gas or oil, and a regulable means 9 for thesupply of atmospheric air.

The burner, in order that it may be combined with the heating tube tosurround the same, is, in the preferable construction, provided at oneend with removable plates, 10, which, when removed, leave the burneropen-ended, in which condition it may, in vertical position, be insertedinto the space between the heating tube 3' and an adjacent leg or columnof the radiator, and then swung downward into horizontal position toembrace the heating tube as shown in Figs. l, 2 and 3, the openings inthe end of the burner permitting the accomplishment of this adjustment.When arranged in the horizontal, heating-tube-encircling position shown,the end plates are inserted to provide a continuous closed fuel passageor ignition chamber l l within the burner.

Combined with the burner and surrounding the heating tube for thepurpose of concoA ceV

fining the flame of the burner rto eXert its greatest eiciency upon thetube and the fluid passing therethrough, is a jacket 12, conformingsubstantially to the external configuration of the tube, and preferablyrounded at its ends, and of cross-sectional dimension conforming to thelike dimension, in one direction, of the column or columns of theradiator, so that when the burner and the jacket or chimney are combinedtogether in relation to the heating tube, they are ineluded in the spacenormally occupied by the radiator and present a structure which does notappreciably differ in appearance from the usual standard make radiator.They are also protected by the outer legs or columns of the radiator,and are therefore free from accident or injury, with which they mightotherwise meet. In order that the chimney may be fitted, in combinationwith the burner, to surround the heating tube, the same is composed oftwo sections suitably connected together, as by means of bolts and nuts13 as shown. When desired, the connection of the two sections of thechimney may be loosened and the chimney removed. I

The chimney or jacket, at its lower end, adjacent the jet orifices ofthe burner, is provided with openings 14, to supply oxygen forcombustion, and at its upper end is provided with a slip-cap 15, havingopenings to more or less register with and therefore more or less openor entirely close similar openings in the jacket, for the purpose ofregulating the draft. The slip-cap may, like the jacket or chimney, beof sectional construction to enable it to be fitted to surround theheater tube.

The desirability of a portable hot water heating apparatus such as maybe shifted from place to place, or installed in various situations, andthe surrounding body of fluid of which may be quickly heated toaccommodate emergencies, where stable or temporary, but efficient andquickly res onding action is desired, has been felt, and t e want isfully supplied by this invention in a simple manner, and ,one in whichthe fuel supplying and confining elements are included within the normalarea of the radiator, protected from otherwise possible injury, andpreserving the normal customary appearance of hotwater radiators.

Having thus described my invention, what Patent is v 1. A portable hotwater radiator, one of the columns of which consists of relatively broadclosely associated walls to compel the iiuid to pass therethrough in athin film, a burner having removable end plates whereby it is adapted tobe positioned to surround said column, and a heat-confining jacketcomposed of sections connected together and arranged to surround saidcolumn.

2. A portable hot water radiator, one of the middle columns of the endsection of which consists of relatively broad closely associated wallsto compel the fluid to pass therethrough in a thin film, a burnerkcombined with and surrounding said column at the lower end thereof, anda heat-confining jacket associated with said kburner and surroundingsaid column, said burner and jacket being arranged within the normalarea of the radiator and protected by the outside columns.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
